생태학에서의 다양성(diversity) 문제는 일반적으로 통용되고 있는 다양성=안정성 (diversity=stability)의 개념과 연관되어 항상 생태학자들의 관심대상이 되어 있다. (Watt 1966). 처음으로 군집(community)의 diversity에 대한 개념을 시도한 것은 Gleason(1922)이며 diversity index의 측정은 Fisher(1943)로부터 시작한다.(in Travers 1979, Hurlbert 1971, Gallucci 1973).
The original concept and theory of Shannon's function H=-$\Sigma$(i-1,n)Pi, log$\_$2/Pi and its applicable domains in ecology are discussed. The confusions exist in use and interpretation of this function are due to: 1. Mixing the idea of proper ecological diversity with that of Shannon's information theory. 2. Confusion of physical or thermodynamical systems with ecological systems. 3. Confusion of the system from which one had calculated function H with the system of which function H is interpreted. It's proposed to use function H for the comparison of community's structure and so, for the distinction of community's evolution (succession) steps.
